Re: need some advice

One simple way is to have a necklace on the cat with pulsed LEDs . Then in each room there are optical sensors. Their outputs are amplified through band pass amplifiers tuned to the pulse frequency.

The alternatives of sound generators on the cat would irritate it. Radio methods are more complex because the receivers can detect through walls.

One joke method would be to have the necklace electrically shock the cat and have meow acoustic detectors in each room. I thought of this method as a door bell. From the sound the human makes you can tell who is at the door.

u can make a beacon which will be using RF frequency and that will send contiunously the signal.

and with good RF level meter u can track the cat

It is not going to be simple.
It will cost a lot of money.

Hi Johnny,
There is an article on page 16 of the Elektor Magazine, December 2005. I found it here:
